使用golangGoogle云端存储身份验证

Question

我有一个去应用程序运行在服务器上。该应用程序需要访问才能将图像保存到Google Cloud Storage。从Google Cloud Storage authentication文档可以看到如何创建一个PKCS12密钥。

我使用

import(
storage "google.golang.org/api/storage/v1" 
) 

如何使用在应用程序与golang“存储”客户如此重要呢？

func ExampleJWTConfigFromJSON() { 
    // Your credentials should be obtained from the Google 
    // Developer Console (https://console.developers.google.com). 
    // Navigate to your project, then see the "Credentials" page 
    // under "APIs & Auth". 
    // To create a service account client, click "Create new Client ID", 
    // select "Service Account", and click "Create Client ID". A JSON 
    // key file will then be downloaded to your computer. 
    data, err := ioutil.ReadFile("/path/to/your-project-key.json") 
    if err != nil { 
     log.Fatal(err) 
    } 
    conf, err := google.JWTConfigFromJSON(data, "https://www.googleapis.com/auth/bigquery") 
    if err != nil { 
     log.Fatal(err) 
    } 
    // Initiate an http.Client. The following GET request will be 
    // authorized and authenticated on the behalf of 
    // your service account. 
    client := conf.Client(oauth2.NoContext) 
    client.Get("...") 
}

func JWTConfigFromJSON(jsonKey []byte, scope ...string) (*jwt.Config, error) 
{ 
    var key struct { 
     Email  string `json:"client_email"` 
     PrivateKey string `json:"private_key"` 
    } 
    if err := json.Unmarshal(jsonKey, &key); err != nil { 
     return nil, err 
    } 
    return &jwt.Config{ 
     Email:  key.Email, 
     PrivateKey: []byte(key.PrivateKey), 
     Scopes:  scope, 
     TokenURL: JWTTokenURL, 
    }, nil 
}
